Rare in the fossil record are the homobasidiomycetes (a taxon roughly equivalent to the mushroom-producing species of the agaricomycetes). Two amber-preserved specimens provide evidence that the earliest known mushroom-forming fungi (the extinct species Archaeomarasmius legletti) appeared during the mid-Cretaceous, 90 Ma. [31] [32]
An atypical mushroom is the lobster mushroom, which is a fruitbody of a Russula or Lactarius mushroom that has been deformed by the parasitic fungus Hypomyces lactifluorum. This gives the affected mushroom an unusual shape and red color that resembles that of a boiled lobster .
In Tennessee, Prehistoric is generally defined as the time between the appearance of the first people in the region (c. 12,000 BC) and the arrival of the first European explorers (c. 1540 AD). The Historic period begins after the arrival of those Europeans and continues to the present.
The ancestors of the Ascomycota genera Geopora, Tuber, and Leucangium originated in Laurasia during the Paleozoic era. [21] Phylogenetic evidence suggests that most subterranean fruiting bodies evolved from above-ground mushrooms. Over time mushroom stipes and caps were reduced, and caps began to enclose reproductive tissue.
Western Tennessee was also submerged by tropical seawater at times during the ensuing Tertiary period of the Cenozoic era. This sea was home to molluscs. [1] A few foraminiferans from Eocene Tennessee were preserved in the state's fossil record. [7] On land, Rivers also flowed through the state. Tennessee was variously covered in forests and ...
Gondwanagaricites (meaning "Gondwanan mushroom fossil") is an extinct monotypic genus of gilled fungus in the order Agaricales from the Early Cretaceous Crato Formation of Brazil. [1] It contains the single species G. magnificus , and it is the oldest known mushroom fossil known to date.
A recent molecular study proposes that it had an ancestral origin in the Siberian–Beringian region in the Tertiary period, before radiating outwards across Asia, Europe and North America. [38] The season for fruiting varies in different climates: fruiting occurs in summer and autumn across most of North America, but later in autumn and early ...
March 5 – Tennessee's first case of COVID-19 is confirmed in Williamson County, marking the start of the COVID-19 pandemic in Tennessee. 2023 March 27 – A mass shooting occurs at a private Presbyterian Church in America parochial school in Nashville, Tennessee , killing three children, three adults, and the perpetrator.
